| A. Natural Killer (NK) Cell Function | |||
| E:T Ratio | Result | Cytotoxicity | Reference Range |
| 50:1 | 5% | Low | (> = 20) |
| 25:1 | 2% | Low | (> = 10) |
| 12:1 | 2% | Low | (> = 5) |
| 6:1 | 1% | (> = 1) | |
| NK Lytic Units | 0.1 | Low | (> = 2.6) |
| CD16/56% positive | 4% | Low | (7–31) |
| Interpretation: Decreased NK cell function. | |||
